What is the primary function of logical access controls in cybersecurity?

The primary function of logical access controls in cybersecurity is to restrict access to software and data. Logical access controls are mechanisms that enforce security policies by determining who can access certain resources, such as applications, files, and data, based on the identity of users. This includes the use of usernames, passwords, and permissions to grant or deny access based on predefined security levels.

These controls are essential for protecting sensitive information from unauthorized access, ensuring that only authenticated and authorized users can interact with critical systems and data. They help maintain confidentiality, integrity, and availability, which are core principles of cybersecurity.

In contrast, while managing user passwords is an aspect of access control, it is just one small part of the broader function of restricting access to data and resources. Hardware compatibility is not related to logical access controls; it deals with the ability of different hardware components to work together within a system. Enhancing network speed does not pertain to access control but rather focuses on performance and efficiency within the network infrastructure. Hence, the correct answer aligns with the fundamental purpose of logical access controls.
